    Default Problem with Dynamic Load Balancer

    Hi, I'm configuring Dynamic Load Balancer module for Wowza. But after all installation instructions I have an error:
    LoadBalancerServer.processMessage: Invalid start string
    This error repeat with interval 2500ms - load balancer sender message interval.

    Note, that i installed listener and sender on a single PC. I do not exclude that the problem could be here.

    loadbalancertargets.txt:
    localhost,1934,023D4FB4IS83
    HTTPProvider in VHost.xml:
    <HTTPProvider>
    	<BaseClass>com.wowza.wms.plugin.loadbalancer.HTTPLoadBalancerRedirector</BaseClass>
    	<RequestFilters>*loadbalancer</RequestFilters>
    	<AuthenticationMethod>none</AuthenticationMethod>
    	<Properties>
    		<Property>
    			<Name>enableServerInfoXML</Name>
    			<Value>true</Value>
    			<Type>Boolean</Type>
    		</Property>
    	</Properties>
    </HTTPProvider>
    and, lastly - Server.xml
    ...

    Hi,

    Can you provide some more information about your current setup?
    What is the Wowza server version you are using?
